DIY Networks – how to create your own Internet access

The refugee crisis has revealed the limitations of the telecommunications market to offer internet connectivity to people in need. As is often the case when the market fails, citizen organisations have stepped in.

This was made possible thanks to an innovative way of using communications technology: DIY networking.

DIY networking is an umbrella term for different types of grassroots networking, such as mesh networks.

According to Vice magazine, mesh networks not only allow wifi routers to provide signals to wifi-enabled devices, as usual, but also, “routers have the ability to connect to and talk to each other. By ‘meshing’ them, or connecting them together, you are creating a larger wifi zone.”

Artists have been looking at these networks as a way to expand and diversify our communication abilities, while questioning mainstream access to internet.

DIY community networks have been also used as social tools to reconnect citizens, for example, the Sarantaporo.gr initiative in Greece.

Sarantaporo has provided a community solution for affordable internet access, but it’s also a revolutionary model for building networking infrastructure, attracting the attention of academics and institutions.

The Spanish community network Guifi.net even won a European Union broadband award last year.

These networks have an important role to play as a counter to the few corporations that dominate the internet, and also as a way to raise awareness of the challenges of privacy, net neutrality, censorship, surveillance and manipulation.

How does it work?

A wireless router, in essence a special purpose computer, can do more than just connect your devices to the internet. It could host a wide variety of web services, from a simple site to a fully fledged collaborative platform, accessible only to those in physical proximity.

These include a virtual announcement board for a block of apartments, an online guestbook for an urban garden, a file-sharing platform for a workshop, and many more creative uses of “self-hosted” web applications, like WordPress, Owncloud and Etherpad that anyone can host on a private web server.

These services are accessible through the router’s wireless antenna announcing a network name, a Service Set IDentifier (SSID), exactly as it works when you connect to a free or home wifi. They can appear automatically on a splash page or captive portal when you open you browser (as is often the case in airports, cafes and hotels).

If the router is equipped with a second antenna, it can easily connect to a similar router residing in the coverage area whose size depends on the type of antenna and environmental factors.

The first antenna can then be used to allow people with their personal devices to connect. And the second to exchange information with the neighbouring router. Each router then becomes a “node” in a small network: anyone who connects to one of them can access the services offered by, and people connected to, the other as well.

As more nodes get connected, larger areas are covered, and a community can be formed, initially by the owners of the nodes and eventually by everyone in the area.

Of course, you cannot easily build a whole such network by yourself, but you can build yourself a single network node using cheap hardware (such as a Raspberry Pi) and free self-hosted software for installing the set of local services and applications of your choice.

Personal networks

It is perfectly legal, in principle, to operate such a node on its own, attached to your balcony or inside your backpack. This could be your personal network inviting your neighbours, fellow travellers, or any strangers sharing the same public space.

The presence of an invisible digital space can be announced through physical urban interventions: a visible marker on the device itself, a QR code, a poster, even through artistic performances or direct face-to-face communication.

Anyone in proximity can join without the need for credentials or other identification, except for being there, and without the need of any internet connection.

Polylogue allows people in proximity to post short messages and see them printed live on a piece of paper that as it advances, gets shredded on the other end. A sort of hybrid, real-world Snapchat.

Soon it will be possible to build and customise a wide variety of such DIY networks using the MAZI toolkit.

Community networks

Community wireless networks have been under development since the late 1990s by tech enthusiasts and activists advocating for a more open, neutral and democratic internet. They include a mix of local services, such as file sharing and live streaming (AWMN.net and Ninux.org) and the provision of internet connectivity.

Freifunk, WlanSlovenja, Sarantaporo.gr, and many more focus on this aspect.

There are also important differences related to the governance model and the concept of the community itself.

Freifunk follows the “free internet for all” approach and depends mostly on voluntary contributions of their members to offer internet connectivity.

On the other hand, Guifi.net places significant focus on the concept of the “commons” implying concrete boundaries and resource management rules.

It has developed a unique model in which the network infrastructure, including fibre cables, is treated as separate from the services they are involved with providing.

The success story of Sarantaporo

The Sarantaporo.gr Community Network in Greece represents another type of community network, deployed in rural areas with limited or no connectivity – places where the free market fails.

It has provided broadband internet to around 15 small villages in Elassona municipality, but most importantly has raised awareness and hope about building communities of commons in Greece.

The main concern today is to include more local people in sustaining the network, providing suitable legal, economic, and political tools for ensuring its sustainability, but also shifting the focus beyond internet access and towards possible local services that could be offered over the existing common infrastructure.

When corporations move in

It is not only grassroots communities, researchers, engineers, and civil society organisations that make efforts to bring internet access to all.

Such platforms have the power to become the only online places that people visit, at a huge price: our privacy and self-determination.

So, a very challenging question is raised for community networking activists: to which internet are they helping people to connect? And why should their offers be chosen over more mainstream, easily accessible, ones?

The answer to these questions reveal a tension between the immediate need to provide access for all and the need to make sure that the internet is built for the common good and not the interests of a few global corporations.

Building local alternatives can play a key role in creating necessary net-diversity and serve many important practical, political, and social purposes.
